A case of identity: Kerberos
Question for our time: Who are you, and can you prove it? Increasingly, the computing solution for these questions in these times is Kerberos, a system of "strong authentication" for computer users invented at the Massachusetts Institute of Technology, and already operating at many universities and several Department of Energy national laboratories.

Structural biologists provides a close look at ribosomes
Biologists working at Argonne’s Structural Biology Center (SBC) recently examined components of these protein factories with X-ray crystallography at resolutions high enough to determine the position and interaction of individual atoms. These images are the culmination of four decades of work in elucidating how the ribosome creates proteins.

Tiny particles cause big stir
Emitted as the result of thermonuclear reactions in the core of the sun and supernovae, the ghostlike elementary particles called "neutrinos" usually travel unnoticed through space, in immense numbers and across vast distances. However, the discovery that these erstwhile phantoms have mass and are polymorphous generated substantial notice from the media on Earth.

Microtools for the nanoworld
Most of what we call nanotechnology involves hundreds or thousands of atoms but in a nanometer there's enough room for three atoms. If we are going to achieve real nanotechnology, we are going to have to learn how to put atoms together one at a time.

Beyond alchemy and the Wright brothers: Nanosecrets of everyday things
t's their nanostructure that makes many crucial materials useful, and chemical processes essential to everyday life routinely do their work on the nanoscale. There's a lot more to nanoscience than building itty-bitty widgets. Catalysts are "helper" substances that promote chemical reactions without themselves being consumed. Nature's catalysts, enzymes, assemble only specific end products. Industrial catalysts are rarely so precise.

Dendrimers: Branching out into realms of molecular architecture
Dendrimers may well become the flagship of nanotechnology's building blocks, a class of polymerized macromolecules that have the potential to provide the most exquisitely tailored forms and functions ever realized outside of nature.

Nanotubes: Superhard, superstrong, super useful
Not only do nanotubes offer a full range of electrical and thermal conductivity properties (they conduct heat better than any other known material), they're also about a hundred times stronger than steel and more durable than diamonds. Their potential for use in electronics is nothing short of mind-boggling: if all the nanotubes that could be packed into a one-half-inch cube were to be laid out end to end, they would stretch some 250,000 miles.

Award-winning gasoline reformer is a catalyst for change
Instead of spark plugs and cylinders, environmentally friendly fuel cell engines may be under the hoods of the cars of the future. But first, scientists must find a practical and economical way to supply the hydrogen gas needed to power them. Chemical engineers at Argonne have developed and patented a compact fuel processor that “reforms” ordinary gasoline into a hydrogen-rich gas to power fuel cells.

3-D holographic scanner for better airport security
The September 11 terrorist attack on the World Trade Center in New York and the Pentagon in Washington, D.C., using hi-jacked commercial airliners has sparked stringent security measures at airports across the nation. Passengers and their luggage are being physically searched before boarding every flight.

Tools for healing
Discoveries in physics have helped forge dramatic advances in cancer treatment for over a century. In 1950-54, according to the National Cancer Institute, the five-year survival rate for all cancers was 35 percent; by 2000 it was 59 percent. With early detection and treatment, the five-year survival rate for screenable cancers is now 80 percent.

Tools for biomedical research
At the forefront of biomedical research, medical scientists use particle accelerators to explore the structure of biological molecules. They use the energy that charged particles emit when accelerated to nearly the speed of light to create one of the brightest lights on earth, 30 times more powerful than the sun and focused on a pinpoint.
